Makes the camera and mouse input feel snappier when interpolation is on. Camera position is still interpolated but the rotation/mouse look is not interpolated anymore.
In it's current iteration (Demo V2) entirely disabling interpolation from main menu fixes floaty mouse look issue but makes camera jitter when you move (at 144hz with vsync). This mod basically makes camera behave like when interpolation is off for looking round with mouse even if it's turned on in the menu.
Helps with motion sickness when used with no head-bob and high FOV.
